论文摘要
本文提出了一种主动干扰拒绝控制(ADRC)方案,具有改进的分数扩展状态观察者(IFO-ESO)。基于新的ADRC方案,高阶系统的开环传递功能可以大致呈现为所谓的Bode Bode的理想转移功能,其封闭环境的封闭性能较小,其封闭性能是PRONE-PRONE PRONES PROMERTER,该函数的变量更少。 IFO-ESO的设计有助于减少估计的系统状态数量,并改善闭环系统的性能,而不是先前提出的文献中所提出的分数主动扰动抑制控制(FO-ADRC)。与整数积极干扰拒绝控制器(IO-ADRC)和FO-ADRC相比,IFO-ADRC的辅助跟踪控制器具有更简单的形式。频域分析表明,IFO-ESO的估计性能比分数ESO更好,并且时间域模拟表明,所提出的ADRC具有更好的瞬态性能,并且在参数变化方面比FO-ADRC和IO-ADRC更强大。提出的ADRC应用于永久磁铁同步电动机(PMSM)伺服控制系统,并在现实世界应用中演示了其能力。
This paper presents an active disturbance rejection control (ADRC) scheme with an improved fractional-order extended state observer (IFO-ESO).Based on the new ADRC scheme, the open-loop transfer function of a high-order system can be approximately rendered to a so-called Weighed Bode's ideal transfer function, whose closed-loop performance is less prone to the controller parameter variations. The design of the IFO-ESO helps reduce the number of system states to be estimated and improves the performance of closed-loop system over %the previously proposed the fractional-order active disturbance rejection control (FO-ADRC) in the literature. Compared with the integer-order active disturbance rejection controller (IO-ADRC) and FO-ADRC, the auxiliary tracking controller of IFO-ADRC has a simpler form. Frequency-domain analysis shows that IFO-ESO has better estimation performance than fractional-order ESO, and time-domain simulation demonstrates that the proposed ADRC has better transient performance and is more robust against the parameter variations than FO-ADRC and IO-ADRC. The proposed ADRC is applied to permanent magnet synchronous motor (PMSM) servo control system and demonstrates its capability in a real-world application.
